I have found that -5dB or -10dB attenuators must be used on the send or
receive strands between Cisco LX connected switches at relatively short distances of < 1 km over standard singlemode fiber.
Other Vendors' SFPs rated up to 25 km do not need attenuators at distances <1 km.
Cisco standard LX TX between -3dBm and -9dBm RX sensitivity is from -9dBm to -19dBm
Oups typo, RX from -3 dBm to -19 dBm -- Pierre-Yves Maunier
